Paper Abstract

Photochemical production of electronically excited NO(A2:?) was studied in mixtures of ozone(03) and hydrogen azide(HN3). Rate constants for kinetic processes forming electronically excited NO(A) following a 248 nm laser initiation pulse were calculated from the temporally and spectrally resolved NO(A-X) emission. NO(A) is formed by the following two-step process: 0(1D) + HN3 --> OH + N3, k = 3.2+1.0 x 10-1° cm3 s-1; and 0(1D) + N3 --> NO(A) N3; k = 1.0+.3 x 10-1° cm3 s-1. Emission from vibrationally excited NO(A) up to v' = 2 was observed in the region of 200 nm - 250 nm.
